I appreciate that this is only a tantalising taste. But you cannot expect them to release all the detail of hard won science data until they have had time to analyse the results and write (hopefully) erudite, peer reviewed papers.
This is the same policy followed by the Rovers. Release raw jpeg but save the science data until they are ready to publish. And the outcomes of this approach were absolutely outstanding, epitomised by the Mclennan and Grotzinger papers on the geochemistry and provenance of Eagle and Endurance.
And the determination of the ph of the soil is a huge result, being a key data point in validating the explanation for the Viking results.
